Abstract: PURPOSE:To inexpensively produce a rigid fiber board which improves a strength, by a method wherein a deep drawing is conducted by forced-pressing a rigid fiber board into a cavity mold by a core mold from a relatively soft plane surface side tightened by an air bleeding net. CONSTITUTION:A soft fiber layer a2 is placed in a cavity m2 so that its plane surface side points to a core m1 side of a mold M, the core m1 moves downward to forced-press a rigid fiber board A into the cavity mold m2 in a condition to heat it at about 200 deg.C.

Abstract: PURPOSE:To prevent damage due to idling by reducing the torque through an idling limiter based on the difference between a motor voltage determined from the features of a DC motor and a motor voltage obtained from a speed generator fixed to a driven wheel. CONSTITUTION:A DC voltage is applied from a stringing 1 onto the armature windings 6, 7 and the field windings 10, 11 of two DC motors through choppers 8, 12. Conduction rates gamma of the choppers 8, 12, terminal voltage Ec of a filter capacitor 5, armature current IM, and internal resistance RM of a main motor are then operated 28-30 in order to determine a motor voltage(EM1+EM 2)=gamma.Ec--2IM.RM. On the other hand, the speed V of a driven wheel 32 detected 35 through a speed generator 33 is multiplied 36 by a flux PHI(if) which is obtained by converting 31 a field current (if), thereby obtaining a motor voltage (EM1'+EM2').

According to the constitution, damages due to idling can be prevented easily.

Then a function for evaluating the possibility of the trouble which includes the index as a variable is calculated for each section and the section where the value is maximum is located as a trouble section. In this case, the current is handled as the vector quantity and the phase is handled as the scalar to make the current value difference clear. For the purpose, a GW current distribution diagram is analyzed by using this function to locate the trouble section, and then even if the GW current distribution diagram deviates greatly from a logical value, the locating accuracy never decreases.
